DUMP-CAB.

rammed May 21, 1912 Application filed November 14, 1807. Serial No. 402,181.

To all whom it may concern:

Be it known that I, JosEPH R. BOWLING, a citizen of the United States, residing in St. Louis and State of Missouri, have invented a certain new and useful Improvement in Dump-Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to prov de a dump car having a plurality of doors with means for releasing any door or doors at will, the remaining door or doors continuing locked, The invention, though not so limited, 1s well adapted for cars having dumplng doors forming a portion of the load-carrying floor, such doors being supported b hooks carried by the sides of the car whic engage floor beams projecting from the door. The invention is herein shown as applied to a transverse dumping car of the type shown in application No. 391,900 of Frank S. Ingoldsby, wherein the doors are transverse and are provided near their 'meeting edges with projecting floor beams which the hooks on t e sides of the car engage. In the present illustration I have shown three pairs of such dumping doors.

The invention consists broadly of door- 80 locking mechanism adapted to release any of a plurality of doors, and, more particularly, such invention as applied to cars having side supporting hooks.

The invention is hereinafter more fully described and its essential characteristics set out in the claims. In the drawings, Figure 1 is a side elevation of a car having my invention applied thereto; Figs. 2 and 3 are perspective views of the upper end of a supporting hook and the operating link, showing the same in two positions; Fig. 4 is a perspective view of the pin for locking the hook either to the operating link or the stationary bracket.

Referring to the drawings by reference numerals, 10 represents the car side, which is shown as' a plate girder having on the upper chord 11, the lower chord 12 and vertical stifieners 13.

14:. represent the dumping doors, of which three pairs are shown, these doors being mounted on transversely arranged hinges 15.

16, in dot-ted lines, represents inclined end floors leading to the endmost doors and 17 indicates transverse shedding beams between intermediate doors,

-Each door is shown as provided near its free edge with a floor beam 20 which braces and stifi'ens that edge and extends beyond the car side for engagement with sup rting and locking levers or hooks. hese hooks, designated 21, are pivoted to the side of the car in a suitable manner and ,have the r upper ends connected by links with a main operating lever 28. It is to be understood that the same system of levers and links is provided on the opposite side of the car. The operating lever, however, is referably employed only on one side 0 the car, while on the other side there is an arm similar to the portion of'the operating lever between the link and the pivot, this arm being connected with the-operating lever by a transverse rock shaft rigid with both of them.

The above described car is shown and claimed in the application referred to. That application also shows and claims means for raising the doors to closed position. Any suitable raising mechanism may be associated with my invention.

To enable any of the pairs of doors shown to be released independently of the others, (or the independent release of sin le doors, where single doors are employed I provide the peculiar connection between the hooks and their operating links which is the gist of the present invention and will now be described. As shown at 25 each lever or hook is forked at its upper end. The operating links 26 and 27 (connected with the lever 23 by a link 24:) lie within these forks. Suitable bolts, rivets or other pins 28 carried by the levers project through slots 29 in the links. These pins 28 normally stand at the end of the slot most distant from the o erat-in lever.

30 indicate plnsvwhich areadapted to extend through holes 31 in the links on the other side of these levers, this construction acting to practically pivot the levers to the links, so that these levers may be operated in the usual'manner by throwing the-main lever,

Above each lever 21, and secured to the side of the car, is a stationary bracket 35, and the upper end of the lever isbent laterally as at 36' to stand beneath this bracket. The bracket and the lateral bend in the lever are each provided with holes 37-38. Now

if the pin 30 be removed from the link, and

instead be passed through the bracket and from'the lever and may thus operate the other levers independently; The slot 29' ;allows the link movement to. swing the engaged levers 'sufiiciently to release the doors.

It will be'seen that the-levers'for any of the pairs of doors may be locked, allowing the main lever to release the other two. Thus in the embodiment shown any pair of doors may be dumped leaving the other two pairs locked, or any two pairs may be dumped (the two nearest either end, or the two extreme pairs) leavingthe other pair locked, orall three pairs may be dumped at once. To enable this universal independence of operation the link 27 to the far pair of doors is connected by a knuckle 39 with the link 26. The link 24 connecting the link 26 with the operating lever also has a jointed connection.

It is to be noticed that ion the closing movement the ends of the slots 29 come into positive engagement with pins 28 on the levers 21, so thatany of these levers which may be thrown forward when the doors are dumped are certain to be brought back .to their locked position when the links are returned to their normal locked position. This is a "aluable feature, for it insures all the doors being locked when 'the main lever is in place and prevents any discharge of any section of the load without destroying the seal which holds the main lever.

To hold the pin 30 in place in either position, it is preferably provided with a tongue 41 which is adapted to pass through a corresponding recess 42 in the sides of the openings 31, 37 and 38. The pin is shown as bent at right angles, so that the weight of its end 44 when it is in the link automatically swings it by gravi into position where the tonguepasses be d the groove and so holds it against displacement. The end of this bent portionis provided with an eye 46 by which it may be connected by chain 47 with a suitable point as the bracket 35. This chain is loose enough to allow all the required movement of the link and lever. When the pin 30 is in place in the bracket 35 for holding the hook' stationary, the weight of the chain keeps it in position, so that the tongue is out of alinement with the groove 42. The eye 46 may also furnish convenient means for the passage of a seal ing wire or band into the opening 48 in the bracket 35 in which the chain is anchored, or into the slot in the link as the case may be, thus preventing any undetectedtampering with the load. I

I have shown thereleasing mechanism as applied to a'transverse dump car. It is to be understood, however, it is equally adaptable to cars of the standard Ingoldsby type having a central longitudinal member and wherever there are a plurality of doors which it is desired to release in universal independence.
